You probably don't need ereg_replace (though if I did, I'd actually use preg_replace), you can probably do it more simply with str_replace. But first you have to know what characters you're actually getting. Say they are '*', '_', and '~' (just an example), then you can do it easily with: $newstring = str_replace(array('*', '_', '~'), array('-', '-', '-'), $string); Or with: $newstring = preg_replace('/[*_~]/', '-', $string); Another approach would be to replace all non-alphanumeric characters (other than commas) with a '-', then you are treating all punctuation characters as dashes: $newstring = preg_replace('/[^a-zA-Z0-9,]/', '-', $string); But that might be overkill ... -- Tom
